<tt>Hello<br>
<br>
I have the solution for my problem. It was that I wanted to make a
Scatter Plot with a logaritmic line and with others points alone
(without lines). To do that I defined two series and two diferente
shapes and strokes:<br>
<br>
</tt>
<blockquote><tt>Stroke[] strokes = new
Stroke[]{LineChartProperties.DEFAULT_LINE_STROKE, null};<br>
Shape[] shapes = new Shape[]{new Ellipse2D.Double(), new
Ellipse2D.Double(0d,0d,5d,5d)};<br>
</tt></blockquote>
<tt><br>
Note that the second stroke is null, I will explain it below. The
first shape is an elipse with no width and height because I don't want
to see the points. I want to see only the logaritmic function.<br>
<br>
As I said above, the stroke is null because for some series I want to
display only the points without the line that unites the points. To
make it work I had to modify some lines in ScatterPlotChart class. <br>
I added this conditional in line 182:<br>
<br>
</tt>
<blockquote><tt>if(scatterPlotProperties.getLineStrokes()[ i ] != null)<br>
{<br>
g2d.setStroke( scatterPlotProperties.getLineStrokes()[ i ]
);<br>
g2d.draw( line );<br>
}<br>
</tt></blockquote>
<tt><br>
I hope that it might help someone.<br>
<br>
Bye</tt><br>

list.
I am using some charts of JCharts's libraries and they work very well.<br>
<br>
Now I have to generate a new chart. I am using ScatterPlotAxisChart but
I need to assign a new ScatterPlotProperties for each set of data
points. At this moment the same ScatterPlotProperties applies to the
entire dataset.<br>
<br>
Can somebody help me to modify the method <i>scatterPlotDataSet.addDataPoints</i>
? I think the best way will be add a new parameter to this method with
the ScatterPlotProperties. I know that I will have to change other
classes to handle this behavior.<br>
<br>
<br>
Thanks<br>
